Do you mean coralline algae or nuisance algae?
My systems running with undetectable Nitrates and Phosphates and without algae grazing fish I’m having the same issue. When I dose or add extra food to increase nutrients the algae is faster at utilising it.
I’ve got Tangs in QT once in the main tank they should resolve the issue by grazing the nuisance algae....well that’s the plan! Lol
My tank has been up for 3 years and really all that works is frequent manual removal mixed with nutrient control. For hair algae I just pull it up, turf algae I scrub the rocks in tank with a toothbrush, bubble algae I scrape it off without popping it and suck it up with a turkey baster. Anything else just use a turkey baster to blast it off. The more you remove, the easier it will be down the road to maintain.
Side note since you have tangs:
Do you feed nori? I find that if I'm feeding Nori every day I have a bunch of cyano that pops up. Easy to get rid of, but blasting it off the rocks once a week can be annoying.
I have the same problem, but to be honest it happens in even the healthiest of tanks. Algal growth isn't anything to be concerned about as long as it is not completely taking over your tank. As long as it isn't an outbreak I wouldn't worry too much. Completely agree with keeping hands out of the tank as much as possible. I only remove when I do a w/c (weekly).
Your corals are not going to out compete fast growing algae in the DT for nutrients, unless you have a lot of them, and I mean a lot.Anyone have any tips on getting coral to outcompete algae for nutrients. My corals are hungry, but nutrients available for algae growth??
You have a new tank. Stuff is going to grow. You might like it or might not. Stop feeding the tank is not a good answer. If you dont like the algae in the DT you have some options to get rid of it faster than if you just let it be, since it will prob go away with time. First "manual removal". Second-macro algae in a fuge or in the DT. Third- algae turf scrubber. Fourth - critters like as what goes on in the ocean. As a last resort you can add some chemical junk and kill off some stuff and hope something worse dose not start growing. These are my opinions and your results may vary.Same exact methodology I use. Failed to mention tank is 3 months new and started with dry everything so ugly stage is also front of mind.

I used to have that issue. My tangs don't let a lick of algae grow in my tank now.
I added a fox face and 4 tangs they nip at the rocks and I think to myself.. dude, there is no algae their. The algae is in the little plastic clipWhat’d you do to change that??
